Attachment 3 - Gas Sample Verification.xlsx

This is a gas sample verification attachment that establishes testing requirements and procedures for compressed gases submitted under solicitation 1305M326Q0071 for supply to the National Oceanic and Atmospheric Administration's Global Monitoring Laboratory in Boulder, Colorado.

The document specifies verification criteria for two gas types: Research-Grade Helium must demonstrate nitrogen concentrations below 3% and oxygen concentrations below 2% relative to mass 69, as measured by GCMS analysis at NOAA's lab; UHP Nitrogen must meet 99.999% purity specifications, be clean for use as a Nafion purge gas, be supplied in minimum 200 cubic foot high-pressure cylinders with a minimum fill pressure of 2000 psi, and include standard CGA fittings. Both gas types require submission of four samples for testing at NOAA's laboratory, with a minimum sample size of N200. Gases must be delivered no later than one week after the Government issues the request. Notably, contractors are prohibited from revising their quotations based on the results of this verification process, indicating that sample testing is a compliance and quality assurance measure rather than a negotiation point.
